Brazing filler metals - an overview | ScienceDirect Topics

However, brazing is generally carried out in air, which means that self-fluxing filler metals (copper-phosphorus) or a separate flux must be used. The flux consists of a mixture of various metallic salts, and is applied to the joint surfaces as a high-viscosity liquid, as a paste or as a powder....<<more>>

Flux (metallurgy) - Wikipedia

Fluxless brazing of copper alloys can be done with self-fluxing filler metals. Such metals contain an element capable of reaction with oxygen, usually phosphorus . A good example is the family of copper-phosphorus alloys....<<more>>

Principles for Understanding Heat Treating Materials

Furnace brazing can use an inert atmosphere, with or without flux, a reducing gas, usually without flux or vacuum without flux. Vacuum furnaces are of the retort or bell jar type. As previously mentioned, furnace brazing is the most widely used for high tech joining applications....<<more>>
